Georgetown, Grand Cayman
I always seem to choose the wrong thing to do here! I've been twice and didn't have a great time. I have heard great things about what is offered on this island. Some of the popular choices are:
Kayak & Power Snorkel at Cheeseburger Reef
We felt like we were had on this excursion. We met the guide right outside of the port area. We walked to the beach about 50 feet away. We were outfitted in our life vests, power snorkels, and kayak. My power snorkel gave out after a few minutes. We basically circled near shore. The name of the ref is Cheeseburger Reef because it is near a Burger King. True Story!
